My 4 yr old DS is getting frequent bouts of nausea and sickness and am getting more worried about him. It has been going on for a while where he says he feels hot but has no temp and doesn’t feel hot to touch. He then feels sick and sometimes is. Often starts straight after evening meal times but can sometimes be earlier in the day. Been going on about 3-4 months but has increased in frequency and has now happened 3 times this week and once last week. He will wake up fine again tomorrow and then by evening be unwell again. Thinking low blood sugar or intolerance? Spoke to docs last week and they didn’t give a view but booked in for appt Tuesday. Has anyone ever experienced anything like this before?
